I really like how the fill pattern of the rope lets you see in the animation the decreasing velocity.

  Yeah seems like a nightmare to animate though.

    The smallest pulley on the bottom betrays how it is done. The rope is a line along the side closest to the pulley, the other side of it // the wire pattern are made by attaching triangle(-ish?) shapes to it. Only the bend at the smallest pulley is so tight it shows.

    If your 2D vector graphics system has support for rendering a path style with diagonal hashes across it, and to continue that path across different primitives (line segments, circle arcs) it seems that then the problem is then easy. You just render the entire cable as a path, starting at the fixed end. You render that path that for different positions of the pulleys and there you have your frames, with the diagonal hashes moving at their apparently correct respective speeds.
